Speciflcation of Letters Patent. Patente d Sept. 13, 1921.

Appllcaon filed January 21,4921. Serial No. 438,&19.

To (LZZ whom it may camera: i i

Be it known that I, ALIX SWINTI, a citzen of Poland, residing at Detroit, county of Wayne, and Stateof Michigan, have invented certain new and useful Improve ments in Looks, of which the following is a specification. i i

This invention relates toimprovenents in looks, particularly in looks for the doors of freight or the like, and it is the principal object of the invention to provide a lock which allows an operation of the doors of a car from the roof only, or visible to a crew of a train at all times, and for quite` a distance. i t

It is a frequent occurrence that doors of freight cars which can be locked and unlooked from the sides are opened by unanthorized parties on one side while the attention of the crew of a train was directed to theother side, and that the cars are robbed of valuable goods as silks, eto.

It is the object of the invention to overcome this disadvantage by providing a de vice which allows an operation of the locking mechanism of both car doors by un authorized persons only and within sight of These and'other objeots and advantages of the invention will become more fully apparent as the description proceeds and by nspeotion of the acoompanying drawings i forming a material part of the present disclosure, in which-- Figure 1 is a side view of a freight car' equipped with a looking devioe constructed according to the present invention.

Fig. 2 is a cross-section through the same along line 2--2 of Fig. 1.

Fig. 3 shows in detail View an element for Operating both doors of a car simultane- Fg. 4 is a detail View of a looking bar.

Fig. 5 is a front View of a looking mem ber and its coperating parts on the roof of a freight car.

F ig. 6 is a side View thereof, looking along line 6-6 of Fig 5.

Fig. 7 is a section throu h the looking member taken along line 7-- of Fig. 6.

Fig. 8 is a cross-section through the member taken along line 8-8 of Fig. 7 and Fig. 9 is a detail view of a key use'd to operate the lock.

A freight car, so-called box-car, 10 running with its wheels 11 on rails 12 is provided with the customary sliding side door 13 on the usual, well known runways. A partition 14 is provided in the car near the end of the door opening and the wall of the caris provided at this place with recesses 15 through which ourved fingers' 16 grip over the outer edge of the car door to hold the same in closed position. The inner ends of these fingers are Secured to a vertical rod or bar 17 vertically and rotatably secured in thecar within the space formed by the par-` tition 14 and the car wall; the upper end of this bar 17 is extended above the carroof 18 and provided with a crank handle 19. Two of such bars 17 are provided for each car, one on each side thereof, and the two bars of one car are connected at their upper ends by an Operating rod 20 located on the inside ofthe car.

A socket 22 is Secured to the upper end i of the handle 19 as at 23 Fig. 5, and a roof 18 so that the for-kod barmay be raised 4 in order to disengage its ends 26 and 27 from the body, when a sleeve 30, which normally engages the upper edges of the fork, and which is screwed upon the body 24, is lifted.

The body 24 is provided in its interior with a vertical channel 31 in which a pin 32 i is sliding provided at one of its side faces with a rack 33 while its lower end is pointed as at 34. A radial channel 35 in the body 24 near the upper end thereof allows the Introduction of the shank 36 ofa key 37 provided with a handle or hanger 38 at one end, while its other end is provided with a gear 39 engaging the teeth of the rack 33. A spring 39' Secured with one end to the upper plate 40 of the bod 24 and with its other end to the up er en of the pin 32, tends to normally old the pin in its elevated position withn the channel 31. Near its lower end the body 24 is provided in its interior with a radial slot 41 in alinement with a longitudinal groove 42 in the inner wall of the sleeve 30. A plate 43 is slidably arranged within the slot 41 and engages normally with its outer end flange 44 the groove 42.

On its side face the plate is provided with steps 46 and 47 having inner, beVeled edges adaptedto be engaged by the beveled face of the lower pointed end 34 of the pin 32 for normally holding the plate with its fiange 44 in the groove 42 of the sleeve for looking said sleeve in position on the body 24. It Will be clear that when the pinis lowered against the aotion of spring 39' by means of the key engaging with its gear the raok of the pin and lowering the same to engage the steps 46 and 47, the plate 43 will be drawn against the aotionof the spring 45 toward one side to disengage the fiange 44 from the greove 42 of the sleeve 30, and the sleeve will be free te rotate upon the body 24, and

upwardly so that the forks can be disengaged from the body 24 and the oranks rotated to release the doors. I r

,In ;order to protect the looking devioe, the same is a rranged within a -oasing 49 on the oar roof 18.` r k Having thus described my in-Vention, what I claim as new and desire to secure by Letters Patenta of the United States is,--

1. A -,dev ioe for looking freight car doors,

oomprising a looking red for each' door, fingers on said rod for engaging the door, a bar zoonneoting the looking reds of, both doors, and means on the roof of a car for, looking said looking rod and ngers ntheir oar door looking position and means for unloc king said looking means.

` 2. A devioe ef the character :described for looking :the side doors of freight cars, comprising a looking ;red for each door, fingers en said red adapted' to be prejeoted through reoess in the ear wall for engaging the edge of the oa-r 'door and holding it in closed position, means for oenneoti-ng the looking reds of both car doors, a :orank at the upper end of each looking red, a sooket on said orank, a looking body on said sooket, means engaging said body for holding it against rotation, a sleevefonsaid ,bod y engaging said means to ?look them in their lookingpos'iton, means connected with said body for looking said sleeve, and means for releasing said sleeve.

3. 'Ina a freight oardoor looking devioe, a

5. In a freight car door looking dovioo, means for looking simultaneously both doors of a car, a pair of vortioally arranged locking rods, fingers on said rods to grip over the edges of a door to lock the same, a conimon Operating handlo for both rods, a ora nk on each red, a reoessed sorew-tln'eadod body on eaoh of said oranks, a forked lover seoured to the oar roof to move in vertical direction only and gripping into -the reoesses of said body and means for looking said forked lover against operation.

6. In a freight car door looking dovice, a body having ,an enter screw-thread, a longitudinal and two radial groovos, a sloevo adapted to be threaded onto said body and having a longitudinal inner groove, a spring controlled looking pin having a pointod lower end sliding in said longitudinal groove, a raok on said pin, a key provided with a gear ongaging said rank and adapted to be introduoed through one of the radial. grooves of said body, a sliding plate in the other of the radia-l groeves of said body, a fiange on said plate normally ongaging the Vertical groove in said sleeve for looking the same onto said body, steps on said plato adapted te bo engaged and disengagod by the pointed end of said pin upon the oporation of said key, and a spring for drawing said plate backward te disengage its ilange from the groove of said sleove.

In testimony whereof I have afiixed my signature.
